Make a list of the main findings • Going through your lists, come up with • Positive aspects and • Concerns
Positive aspects of this survey: • large enough sample, • online-so anonymous encouraging people to answer truthfully, • clear definitions of an office worker and a gamer.
Concerns: • Selection method not stated • may not be random • potential for a high non-response rate-(workers too busy) • only young people surveyed but findings extrapolated to “9 million office workers” which may include other age-groups • some ambiguous response options • dubious claim made: “eating lunch at a desk could double risk of DVT” • it is staying seated that increases the risk, not place of lunch
There should be no ambiguity when answering a survey. This ComRes survey clearly defines an “office worker” and “a gamer” but offers the ambiguous response options: very often, fairly often, not very often in questions 9 to 12.

The margin of error is a statistic expressing the amount of random sampling error in a survey's results. The larger the margin of error, the less confidence one should have that the poll's reported results are close to the "true" figures; that is, the figures for the whole population. Margin of error occurs whenever a population is incompletely sampled.
